Product Introduction
Sn45Pb55 tin-lead solder wire alloy is made of high purity electrolytic Yunnan tin gold raw material, and is automatically extruded to form multi-aperture tin wire. It has the advantages of good wettability and high weldability, and is suitable for various automatic soldering machine welding and manual welding processes.
The surface of the solder wire is even and sleek, with a shiny appearance. It has excellent ability to form strong connections quickly and consistently. When used for brazing, it does not create any splashes and leaves behind very little residue. Additionally, it has a transparent and colorless appearance.
